FRAME .FOR RAILROAD VEHICLES.

Original application filed February 15, 1928,. Serial No. 254,369. Divided and this applioation filed April 4, 1928. Serial No. 267,169.

The application for patent on this invention is a division of that filed by the present applicant, February 15, 1928, Ser. No. 254,369. r

This invention relates to frames for supporting the bodies of railroad vehicles, and, while particularly designed for'application in the tenders of locomotive engines, is not limited to such application, being equally adaptable to use in railroad vehicles of other descriptions. The object of the invention is to provide a fabricated frame structure, of

simple and strong construction; comparatively low cost of manufacture; and ready l5 adaptability in. connection with the bodies of railroad vehicles, of various types known in present standard practice.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure 1 is an isometrical view of a tender frame, illustrating an embodiment of the invention; Fig. 2, a vertical transverse section through the same, on the line a a of Fig. 1; Fig. 3, a view, the right hand half of which is a front end elevation, and the left hand half, a. vertical transverse section, on the line b I) of Fig. 1; Fig. 4:, an isomet-rical view, showing a structural modification; and, Fig. 5," a verso tical transverse section, on the line 0 c of Fig. 4.

In the practice of the invention, referring descriptively to the specific embodiment thereof which is herein exemplified, and,

first,-to Figs. 1, 2 and 3, there is provided a fabricated frame structure, herein illustrated as adapted for application in a locomotive tender of present standard practice. The frame comprises two counterpart 40 side frame members, 1, 1, each having formed integral therewith, a plurality of laterally projecting cross tie sections, 1, said cross tie sections, on each of the two side frame members, being of such length as, in the completed frame structure, to abut, and be connected in pairs, in the middle vertical longitudinal plane thereof. The side members and cross tie sections, are herein shown as of channel section, but such specific section is not of the essence of the invention, and any other preferred one may be adopted.

The cross tie sections, 1, of each side member, further from said member, are connected, one to the other, by integral inner longi tudinal members, 1 which extend parallel with the side members, at a distance less than that of the abutting faces of the cross tie sections, so that the said inner longitudinal frame members of one side member do not abut against those of the other.

Flanges, 1 are formed on the ends of the cross tie sections, and the two side members, with their integral associated parts, are rigidly secured together, by bolts, 2, passing through said flanges, or by other means, as riveting or welding, if preferred.

The cross tie sections at the front and rear ends of the frame structure are connected with the sections next adjacent to them, by integral draft gear sills, 1 which extend parallel with the longitudinal members and nearer thereto than to the abutting ends of the cross tie. sections. Spaces are thereby left between the sills, 1*, which serve for the reception of draft and buffing ear elements.

The application of the invention, in connection with a water bottom tender, is shown in Figs. 4 and 5, and accords in all substantial features with that shown in Figs. 1, 2, and 3 hereinbefore described. The minor structural particulars of difference consist in the provision of integral bottom plates, 1, which close the lower sides of the spaces between the side members and the cross tie sections, and of top flanges, 1*, formed on the tops of the longitudinal members, 1 the seam between said flanges being made watertight, and said flanges closing the spaces between said members, thereby preventing the escape of water through said spaces, and providing a water bottom which increases the capacity of the tank that the frame supports.

The invention claimed as new and desired to be secured by Letters Patent is:

1. In a fabricated railroad vehicle frame structure, the combination of two counterpart castings, each comprising, in an integral piece, a longitudinally extending side member; a plurality of cross tie sections, projecting laterally therefrom; inner longitudinal members, connecting the cross tie sections; and means by which the cross tie sections of adjacent castings are rigidly secured together.

2. In a fabricated railroad vehicle frame structure, the combination of two counterpart castings, each comprising, in, an integral piece, a longitudinally extending side member; a plurality of cross tie sections, projecting laterally therefrom; inner longiforming Water storage chambers; and means by which the abutting longitudinal members of adjacent castings are rigidly secured to-.'

gether. I

3. A railroad vehicle frame castlng, compr1s1ng,1n an lntegral piece, a longltudlnally 10 extendin side member a. luralit of cross 2; a P y r tie sections, vprojecting laterally therefrom; inner longttudinal members connecting the cross tie sections, and liaving flanges adapted to abut against-flanges on a counterpart casting; and bottom plates, closing spaces between the cross tie sections, and between the side member and inner longitudinal member and forming bottoms for Water storage chambers.
